Problem Statement
There is an inefficiency in the transports of Distribuidora Montosa De Orizaba, SA de CV, which are approximately 5 trucks that fail daily, these affect the distribution of such product and these setbacks are manifested in economic losses. Trucks transport beer to nearby regions, therefore, if one of these transports breaks down, the product does not reach the consumer. Until today there is no record of observations to predict failures or at least control them.
Comparison table of solution methods
Once the problem is identified, it is necessary to control the process, for which we are going to show some methods that will help us to carry out a control and also techniques that will help us to improve the process and reduce or eliminate our problem. It is worth mentioning that all these techniques are industrial engineering.

Technique |
Description |
Advantage |
Disadvantages |
| 1. Check sheet | Record and collect data through a simple and systematic method, such as the annotation of marks associated with the
occurrence of said mechanical failures. |
· It is used both in the study of the symptoms of a problem, in this case the failures of delivery trucks, as well as in the investigation of the causes and data analysis. · It is the starting point for the development of other tools. |
· Sometimes the data collection time is long and workers' schedules cannot be stopped or delayed. |
| 2. Cause-effect diagram | It is used to represent the relationship between some effect and all the possible causes that can originate it. | · Facilitate the study of truck failures.
· It will help to know what are the possible causes that produce this problem. |
· If the truck mechanical system is not fully understood, the diagram may be inefficient. |
| 3. Pareto diagram | It is a graphical method that helps us determine which are the most important problems in a given
situation and, consequently, the priorities for intervention. |
· It can help us look at minor problems, which may be the cause of most failures.
|
· If a correct interpretation is not made, this tool will be invalid. |
| 4. Histogram | It is a bar graph that shows the frequency with which a series of data or phenomena have occurred or have been presented,
as well as their distribution. |
· Analyze the variation that exists in the behavior of these data.
· It allows us to group and organize data so that they have some meaning and give a better vision to have conclusions and be able to take objective and correct actions. |
· A correct interpretation of the bar graph is needed to make a decision. |
| 5. FMEA
(Analysis of modes and effects of potential failures) |
Systematic process for the identification of potential failures in the design of a product or a process (in this
case of delivery trucks) before they occur, in order to eliminate them or minimize the risk associated with them. |
· Recognize and evaluate the potential failure modes of engines.
|
· If all possible ways in which failures may occur are not identified and examined, this process will not be
adequately evaluated. Therefore the objective will not be met. |
| 6. TPM | Improvement methodology that allows the continuity of the operation, in the equipment and plants by introducing the concepts of:
|
· Guarantees the company results in terms of improving productivity.
· Reduction of waiting time for customers.
|
· Lack of planning and development strategies.
· Need for immediate results, which can lead to missing important steps. · Disagreement due to the growth of staff tasks. |
| 7. Six Sigma | It is a methodology based on statistics for process improvement; focused on reducing their variability , reducing or eliminating defects or failures in the delivery of a product or customer service |
· Focus on the customer for better delivery service.
|
· Six sigma starts from top managers, and if they don't get organized, the methodology won't work.
|
| 8. Deming circle | It is a strategy of continuous quality improvement in four steps (plan, do, verify and act), based on a concept devised by
Walter A. Shewhart |
· It is a strategy that is made based on observation, so it should address the needs of the main
workers who perform mechanical work on trucks. · If followed correctly, continuous improvement will be day by day. |
· Staff should be trained, such a situation causes investments that not all entrepreneurs want to assume. |
| 9. Kaizen | System focused on continuous improvement of the entire company and its components, in a harmonious and proactive manner. | · Improve both the company in general, as well as the maintenance area and its activities that make them up, and the individuals
who make them come true.
|
|
| 10. 9´S | It is a methodology aimed at understanding, implementing and maintaining a system of order and cleanliness in the organization. | · Continuous improvement of working conditions within the mechanical workshop area.
· Workers will be able to work at ease and in less time. |
· The commitment of the workers is necessary, to be implemented and continue to maintain it, if not, it will be
of no use. |
conclusion
To have a clearer idea about our problem and what could cause it, it is necessary to use tools or techniques such as a check sheet and a cause-effect diagram. Once we recognize the origin of our problem well, we will now implement the TPM tool, which is the most appropriate for this case, since it is focused on maintenance, both corrective and preventive, with zero failures as the objective.
